Abstract

The invention relates to the technical field of adjustment of clearances between air cylinders and pistons, in particular to an externally-arranged device of a piston and air cylinder clearance adjusting device for a compressor. The externally-arranged device comprises an outer cylinder body and the piston located inside the outer cylinder body. A piston rod used for controlling the piston to slide inside the outer cylinder body is axially and fixedly connected to the central position of the right side wall of the piston. According to the externally-arranged device of the piston and air cylinder clearance adjusting device for the compressor, internal thread clearance adjusting blind holes and extrusion transmission holes communicating with the internal thread clearance adjusting blind holes are formed inside the piston, internally-arranged piston devices controlled by hexagonal socket studs are fixed inside the extrusion transmission holes, and display tubes matched with the internally-arranged piston devices are arranged inside the piston rod, so that whole clearance adjustment is visual and convenient, the transformation cost is small, meanwhile, airtightness is not affected, andthe application range is wider.

Description

technical field [0001] The invention relates to the technical field of clearance adjustment between a cylinder and a piston, in particular to an external device of a piston and cylinder clearance adjustment device for a compressor. Background technique [0002] Because the working time and working intensity of the reciprocating compressor are particularly large, under long-term high-intensity work, there will be more or less a little looseness between the piston rod and the piston or between the piston rod and the crosshead. If there is no clearance volume between the pistons, a cylinder collision accident will occur between the piston and the cylinder, and if it is serious, the machine will be destroyed, and if there is no clearance volume, the piston will drain the gas in the cylinder every stroke. At this time, the valves of the inlet and outlet of the cylinder are particularly violent and unstable when they are opened, and the damage to the valves is relatively large. A...
